视觉注意是人类和动物赖以生存的重要认知功能。研究具有注意机制的主动视觉计算模型，对探索认知过程初期大范围知觉组织以及具有主动环境感知的视觉计算系统具有重要意义。本课题旨在围绕注意选择中的信息交互问题，探索视觉信息动态协作与组织的有效计算途径，突破视觉目标检测与跟踪的关键技术。主要研究内容包括：针对视网膜各层细胞动态交互协作机理，研究一种新的运动差异性检测模型，为快速检测视频流中独立运动目标提供一种新的动态显著性生成方法；在"物体"尺度上，利用统计结构学习，探讨人类视觉注意中显著性特征的组织方法，研究基于视觉注意的显著性目标检测模型；利用目标的显著性、时空约束、以及目标与环境的动态差异性，结合概率图论，研究鲁棒的显著性目标跟踪模型。经过本课题的组织与实施可为在动态场景中自主行使车辆提供一般性障碍物检测与跟踪方法，对可视媒体内容分析与整理的研究也具有借鉴意义。 中文主题词： 视觉注意;显著性;目标检测;目标跟踪 英文摘要: Visual attention is an important cognitive function for the survival of humans and animals. For exploring large-scale perceptive organization in the early stage of cognitive process and a visual computational system with active environment perception, research on active visual computational model with visual attention should play an important role. This project focuses on the problem of information interaction in visual attention, exploring effective computational methods for dynamic visual information cooperation and organization, and making a breakthrough in the key techniques of object detection and tracking. The major research content involves the following components. First, based on the dynamic interaction and cooperation of different levels of retina cells, a novel motion difference detection model will be studied, which can provide a new dynamic saliency capturing approach for fast detecting of independently moving objects in video sequences. Second, in the scale of "objects", the organization of saliency in human visual attention will be explored, which aims at developing a saliency-based object detection model. Third, incorporating statistical graph theory, a robust salient object tracking model will be studied using the saliency model of objects, temporal and spatial constraints, and the dynamic difference of objects and the environment they are in. The implementation of this project will be able to provide general obstacle detection and tracking approaches for unmanned vehicle in dynamic scenes. Besides that, analyzing and categorizing video sequences can also benefit from it. 英文主题词： Visual Attention;Visual Saliceny; Object Detection; Object Tracking. |
